Puntland state authority said security forces in Garowe have seized four military vehicles, including a bullet-proof car heading to its rival Galmudug.
The detained vehicles are reportedly imported at Bosaso seaport and aimed to travel to Galmudug state-administered southern Galkacyo, according to reports.
Galmudug state of Somalia did not comment on the issue, but it comes as Puntland barred all transpirations from southern Galkayo over security concerns.
Puntland and Galmudug have several times battled in Galkayo over land dispute and security issues, as the two states are members of the federal government of Somalia.
